7) OPERATING INSTRUCTIONS
Keep the inside of the cutter clear of swarf. It restricts the operating depth of the cutter.
• Ensure that the coolant bottle contains sufficient cutting oil to complete the required operating duration. Refill as
required.
• Occasionally depress the pilot to ensure cutting fluid is being correctly metered.
• To start the machine, follow the control panel operation instructions.
• ALWAYS switch off the motor by depressing the MOTOR stop button. DO NOT switch off the motor by depressing the
MAGNET switch.
• Apply light pressure when commencing the cut of a hole until the cutter is introduced into the work surface. Pressure
can then be increased sufficiently to load the motor. Excessive pressure is undesirable, it does not increase the speed of
penetration and will cause the safety overload protection device to stop the motor, (the motor can be restarted by
operating the motor start button), and may cause excessive heat which may result in inconsistent slug ejection
• Always ensure that the slug has been ejected from the previous hole before commencing to cut the next.
• If the slug sticks in the cutter, move the machine to a flat surface, switch on the magnet and gently bring the cutter
down to make contact with the surface. This will usually straighten a cocked slug and allow it to eject normally.
• Apply a small amount of light oil lubricant regularly to the slide and arbor support bearing.
• Cutter breakage is usually caused by insecure anchorage, a loosely fitting slide or a worn bearing in the arbor support.
(Refer to routine maintenance instructions).
• Only use approved neat cutting fluid, do not use water diluted oil. Rotabroach cutting fluid has been specially
formulated maximize the cutters performance. It is available in 1 litre (RD208) and 5 litre (RD229).
• When using the coolant bottle accessory, ensure the machine is unplugged from the power supply, when re-filling.
